UPDATE #2

SECTION OF HIGHWAY 1 WASHES OUT AT RAT CREEK ON BIG SUR COAST

MONTEREY and SAN LUIS OBISPO COUNTIES – A debris flow from the hillside above Rat Creek on Highway 1 on the Big Sur coast overwhelmed drainage infrastructure, flowed across the highway, and eroded the road resulting in the complete loss of a segment of Highway 1 at that location.

Rat Creek is located at PM 30.2 and is two miles south of the Esalen Institute. It is about 1 mile south of the origin of the Dolan Fire in the Dolan Canyon area of Big Sur and is within the burn scar area.

On Thursday Jan. 28, Caltrans crews, working from the north doing a post rainstorm assessment of the roadway, discovered debris flow across the highway at Rat Creek. Before dark on Thursday, the lane on the coast side of the road had washed out.

On Thursday evening, Caltrans entered into a $5 million emergency contract with Papich Construction of San Luis Obispo County to assist with repair of the highway slide out.

On Friday Jan. 29, Caltrans assessment crews and emergency contractors arrived at daybreak to discover that both lanes of the highway had washed out.

At this point the damage assessment team has not issued a report on today’s findings and will continue to work this weekend. The current closure of Highway 1 from Ragged Point to Fuller’s Point just south of Deetjen’s Big Sur in remains in effect.

Businesses on Highway 1 from Carmel to Big Sur and south to the full closure remain open.

Barricades, cones, as well as message and directional signs are in place at both ends of the closure to alert motorists traveling in the area.

There will be alternating lane closures on northbound and southbound Highway 1 from the Camaldoli Hermitage to Big Creek Bridge for work along the shoulder of the highway from 8:45 a.m. to 2:30 p.m. (let me be so bold as to suggest that they may be wanting to check and clean the drains)

This one reminds me of the Rocky Creek slip out of 2011, but with less road. To revisit that one, go back in time here https://bigsurkate.blog/2011/03/17/highway-one-closure-indefinite/

6:00 am — It has been a wild ride the last few days, and even though it is still raining/drizzling, we have been through the worst of this storm and now have a few days before the next ones, which are predicted to be much milder. I will be adding to this post throughout the day, as I did yesterday. I do not expect to have an official report on the slip out at Rat Creek until afternoon, unless Dave gets out there and reports, unofficially.

First thing I note is the slide at Hurricane Point, about 50 feet long. Looks like it will probably be easy to clean up once Cal Trans is rolling at dawn.

These graphs were published last night, Note on the first graph, Three Peaks gauge was not working. It sat at the same numbers all day on Weds and Thurs. But note the highest rain received was at Chalk Peak here in the South Coast of Big Sur.
